Food Additives Content in Selected Snack Foods and Beverages and Public Perception of E-Numbers in Muscat, Oman

The aim of this study is to identify food additives content in selected snack foods and beverages sold in the Omani market and if these additives could pose any health risk. Moreover, a pilot survey was also conducted to assess public perception regarding E-numbers used in these products. The E-numbers printed in the ingredient label of 83 products sold in different supermarket out lets and 250 questionnaires distributed to public were recorded, collected respectively and subsequently analyzed. The results showed that the overall number of food additives used in the selected crisps, biscuits and fruit juices was 46 in which 22 of these additives are found in crisps. Among these additives citric acid is the most common type and used frequently in all products. Some of the additives used such as monosodium glutamate and food colorings could pose a health risk upon excessive consumption. Lack of risk and benefit perception in the public regarding E-numbers is the main conclusion of the survey. Furthermore, significant (p<0.05) difference in knowledge and attitude between Omanis and expatriates was also observed. The synergistic effect of food additives on health due to the excessive content of additives in the selected products needs more attention.
